A converter circuit and methods for operating the same. The converter circuit includes a supply voltage, a capacitor, an inductor, and four stacked switching elements. Each switching element is adjustable from a low resistance state to a high resistance state by a control signal. The inductor outputs current to a circuit load. The circuit may be operated in a first mode such that the output is adjustable between the supply voltage and half the supply voltage. Alternatively, in a second mode of operation, the output is adjustable from half the supply voltage to a ground voltage.
